From d7aea17d2e606249c2a3e8495f70bb4e47e11ed8 Mon Sep 17 00:00:00 2001 From: Yang Xiwen Date: Tue, 20 Jan 2026 03:07:18 +0800 Subject: [PATCH] drivers: core: device: set new parent when old parent is NULL The current logic does not update the new parent in device_reparent() if old parent is NULL. The behavior is not desired. Fix it by setting the parent in this case.
